Energy and Energy Transfer

Front

What is energy?

Back

Energy is the ability to do work or cause change. It exists in various forms, such as kinetic, potential, thermal, chemical, and electrical.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion. It depends on the mass of the object and its velocity.

Front

What is potential energy?

Back

Potential energy is stored energy based on an object's position or state. It can be gravitational, elastic, or chemical.

Front

What is gravitational potential energy?

Back

Gravitational potential energy is the energy an object possesses due to its height above the ground. It increases with height.

Front

What is chemical potential energy?

Back

Chemical potential energy is the energy stored in the bonds of chemical compounds, like food or fuel.

Front

What is energy transfer?

Back

Energy transfer is the process of energy moving from one object or system to another, often resulting in a change in form.

Front

What is an example of energy transformation?

Back

When a battery powers a toy, chemical energy is transformed into electrical energy, which then powers the toy's movement.

Front

What is thermal energy?

Back

Thermal energy is the total kinetic energy of particles in a substance, related to its temperature.

Front

What is electrical energy?

Back

Electrical energy is the energy of moving electrons, commonly used to power devices and appliances.

Front

What is mechanical energy?

Back

Mechanical energy is the sum of kinetic and potential energy in an object, related to its motion and position.
